r In the accompanying drawlngs, which are hereby made a part. hereof:

Figure 1 is an elevation of a metal working machineas is necessary to illustrate theapplica'tion of my improve ment when the. machine is equipped tog-bend and cut flat stock or bars of angular forms,

in cross section. r V p Fig. 2 is a similar view of the same-ywlth the working parts in difi'erent positions.

Flg. 3 comprises enlarged detail views of the lower cutting die included in the embodiment shown in Figs. 1 and 2. i 7

Fig. 4: comprises detailenlarged views of the upper cutting die of said embodiment.

Figs. 5 and 6 are views, similar to Figs. '1 and 2, and showing the machine fitted for 1 bending and cutting stock or bars of angu lar cross section.

Fig. 7 comprises detail enlarged views of the upper cutting die'of the machine as 1 shown in Figs. 5 and 6. 1 1 1 Fig. 8 comprises enlarged detail views of the combined die-support andstock'support emeraced in the embodiment of Figs, 5

6. I have electedto show my improvement in known eye bender machine,which is not of my invention per se, but which machine constitutes the subject of Patent'No. 582,283, dated May 11, .1897, but it is to be understood in this connection that my novel dies may be embraced in and combined with the working parts ofanalogous metal-working machines, without involving departure from the scope of my invention as defined in my appended claim.

-As illustrated inFigs. 1, 2, 5 and 6,

- machine alluded to, comprises a reciprocadie 6,

la he land against the. gage 5., andithe machine is then operated, 1 whereupon the, head 1 descends and clamps the st0ck, an d. gives it its initial bend. .,At. the same timeithesgage 5 isturned ldown out,of the. way. 81 Therevolving die 3 thenwipes the stock around the.

mandrel l andthe organized mechanism is reversed whereupon the-head l'is elevated 01- retracted, and the emandrele is withdrawn soasto permit-the completed piece to, ,dr p to the floor or .into :a receptacle pro,- vided for the reception of the same. This mode of operation, it is tobe understood, is, also true of the machine when the capacity of the machine is increased by the embodiment of my improvement, as will be now described. In the embodiment of my invention shown in Figs. 1 and 2, the machine is intended to handle roundstock, and, therefore, the head 1 is equipped at? with an upper cuttin die the said die being provided with a ke rf of semi-circular form in cross section in its lower edge, asshown in Fig. 4., and being fastened to the head 1 by screws or other suitable means, driven through the apertures 8, Fig. 4, and into the head 1. Also in said embodiment, the stationary die 6 has fastened to it a lower cutting die 9, Figs.

1, 2 and 3, the fastening being elfected by screws 9 or other suitable means driven through slots 9 in the die 9 and into the stationary die 6, and'the said die being characterized by a slightly upturned inner end 10, a transverse groove 11 therein, and a longitudinalgroove or channel 12, of semicircular form in cross section, the latter to seat the round bar or stock, as shown in Figs l and 2. a

The operation of the machine provided withthe dies 7 and 9 is that before described with the addition that incidental to the downward movement of the head 1 as described, the bar will be cut synchronously with the .initial bending of the same, after the manner shown in Fig. 2, and in that way the face plate 2, a'gage 15,;and.af stationary operation of the a bendmg machine purely, the :operatorplacesthe bar or rod ,togbe bent over the imandrel.

the production of the bent and cut article Will be materially cheapened.

In the embodiment shown'in Figs. .5, and

6, the head '1 is provided'with an upper cutting die 7 of the type shown imEig. 7, and

a bracket 13 is connected to the stationary die. 6, on which bracket ,is. fastened a lower cutting die 9 Figs. 5 and 6.

The machme shown in Figs. 5 and 6-1s adapted to cut and bend flat stock, but its operatlonisthe same as the round stock maclnne ofwlhgs, lqand2,1 audit is therefore deemedunnecessary to reiterate the same-H It will be gathered from the foregoing that. a bending-machine equipped in accordance with my invention 1s simple and inexpensiveiii-construction, andyet is adapted,

to; perform the two-fold function of cutting andibending inone operation, with the re? sulttthathandling of the stockis reduced to aiminimu m, and the .cost of production materially cheapened;

Having described a my invention, What, 'I-

claim and desire to secure by Letters Patent, is:

An organizedmechanism in a metal 'working machine, eomprising a stationary die, a head movable-toward and from the station, ary dieand constructed and arranged in ,cooperation Withthe same to clamp andLinitially bend the stock, a lower cutting die on the stationary die and. an upper. cuttingdie on the in ovahle thead; saidcutting idies heiniq disposed back of the stationar die-and-hea forward portion; of stoclr subsequently to} the clamping and initial bending, and cut ting of the stock andfthen release said portion and-permit it 'to drop, whereby Whenthe movable headrecedes from the stationary die, the fully bentcut-off 'portion of stocklis free to drop, and the folloiiving por, tion of stockinay be H Cl VBIII CQdi'bElTWG BIl the stationary die and the hjeadandto the gage inreadiness for*anotlieroperation? In testimony whereof I have hereunto set m hand in presence oftwo subscribing- Wit nesses.
